摘要

Two-dimensional (2D) materials and ultrathin nanosheets have attracted tremendous research interests [1-4].Exfoliation of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) with 2D coordination structures is emerging as a viable strategy for preparation of new types of 2D materials [5-8].The relatively weak bonding within and strong interactions between 2D coordination networks are the main problems for successful exfoliation [9].Pretreatments of the layered MOFs to expand the interlayer distances can be helpful [10-12].Capturing the exfoliation intermediates and visualizing their structures are valuable for understanding the exfoliation mechanism and confirming the structures of the final 2D materials [11,12].
